Generally speaking a precipitate is something that will form as a result of the reaction. It generally is a solid material.

Sodium and nitrates are soluble so Calcium Phosphate would precipitate out....

Which of the following will increase entropy in a reaction?

Lapatulllka [165]

B. Heating up the reaction will increase the entropy of a reaction.

<h3>What is entropy?</h3>

Entropy is the measure of the degree of disorderliness of a system.

Entropy is also the measure of a system's thermal energy per unit temperature that is unavailable for doing useful work.

S = ΔH/T

where;

S is entropy
ΔH is energy input
T is temperature

Entropy increases in reactions in which the total number of product molecules is greater than the total number of reactant molecules.

However, entropy increases as temperature increases. Thus, heating up the reaction will increase the entropy of a reaction.

Answer:

An atom is made of up subatomic particles called protons, neutrons and electrons. The center of an atom is called the nucleus and is where the protons and neutrons are held while electrons orbit the nucleus in orbital shells. A electron has a negative charge, a proton has a positive charge, and a neutron has no charge (neutral).

The atomic number of a atom is the total amount of the atom's protons. In a neutral atom (Not an ion), the amount of electrons is the same as the protons. Therefore, the atomic number also tells the amount of electrons in the atom.

A ion is a negatively or positively charged particle due to the giving or taking of electrons with one or more atoms (Called an ionic bond). An atom that gives away electrons becomes positively charge because that atom now has more protons than neutrons. An atom that takes an electron becomes negatively charge because that atom now has more electrons than protons.

Atomic Mass is the sum of an atom proton and neutrons. To determine how many neutron an atom has, subtract the atomic mass from the atomic number. Electrons do not play a part in atomic mass as their mass is 1/1,836 of a proton's mass.

A isotope is two or more forms of the same element that contain equal amounts of protons but different amount of neutrons.

Nitriles can be converted into carboxylic acids. how would you use ir spectroscopy to monitor the progress of this reaction?

Lady bird [3.3K]

Fats or oils are created when the hydroxide group of glycerol combines in a dehydration synthesis process with the carboxyl group of fatty acids.

<h3>What is dehydration ?</h3>

Your body loses more fluids when you are dehydrated than you are taking in. If unattended to, it could get worse and become a serious problem.

When you don't drink enough water or lose more than you take in, you become dehydrated. Sweat, tears, vomiting, urination, and diarrhea all cause fluid loss. Climate, level of physical activity, food, and other variables can all affect how severe dehydration is.

Dark urine, decreased urination, headaches, weariness, dry skin, decreased skin turgor, and poor focus are all indicators of dehydration.
